I just bought this Truck about 3 Months ago, now I am getting a Slight Rod Knock during Acceleration from underneath the Motor. I first thought it was an Exhaust Leakor just by Tapping the Gas. I am have an appointment with the Dealer Tomorrow. I has 42,000 miles. Has anyone heard of a Motor going bad so early ?:mad:

It may just be spark knock from using too low of octane. Get a tank of premium and see if it goes away. If you have a rod knocking, you'll likely hear it more than just when accelerating.

i had a horrible noise that i thought was a knock, but the dealer said it was an exhaust leak at the header. he said its a pretty common problem. mine had like 95K miles at the time and it looked like it had the factory header gaskets still.
